- To all whom it may concern:

Be it known that I, THo'M'As M I DAY, citizen of the "United *States, IBSldlIlg at Windfall, in the county of T iptonand State of Indiana,- haveinventeda new and useful Door Check, of which the following '18 'a specification.

This invention relates to 'door checks and aims to provide novel means for checking the movement of a closure to eliminate slamming caused by rapid closi'ngthereof.

. The primary object of'the-invention 1s to provide a device of this character which is comparatively simple in construction and one which embodies few parts, reducing the cost of door checks to the minimum.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is a side elevational viewof a closure check, constructed in accordance with the invention and showing the upper portion of a closure as supplied with-a spring arm contacting with the pivoted arm of the check. I

Figure 2 is a plan view of the check.

Figure 3 is a fragmental elevational view of the upper extremity of the spring arm.

Referring to the drawing in detail, the reference character5 designates a closure supplied with the spring arm 6 forming a part of the door check.

This spring arm 6 is formed of a length of flexible metal provided with suitable eyes to accommodate the securing screw 7 by means of whichthe arm may be secured to the outer surface of the closure, adjacent to the upper end thereof.

The arm 6 is formed with a coiled portion or loop 8 lending resiliency to the arm, the upper extremity of the arm being shown as formed into a keeper 9 and extended above the upper end of the closure 5.

The reference character 10 indicates the supporting arm of the check proper, and

embodies a right angled extremity 11 designed to be secured to the door frame, adjacent to the upper end of the door, so

that when the door orclosure moves to its closed position, the arm -6 will contact with the door checlrto accomplish its end.

Forming apart of -the'door check is a pivoted arm 12 supported' by the arm 10 as *by means of thepivot pin 13, whereby the 1 arm 12' may be permittedto pivot-in 'a verticalplane. A'laterallyextendi-ng pin 14: is formed onthe arm 12 and moves in the .cutout portion 15of the arm 10"to restrict movement ofthe arm 12 in one direction. pin-16-is also carried 'by' the arm-at apoint adjacent to the pivot pin 13, the pin 16 being designed to contact with the shoulder 17 when the arm 12 is moved downwardly causedrby its contact with the spring arm 6.

The outer end of the arm 12 extends upwardly as at 18, and is providedwith an inclined end wall 19 lying within the path of travel of the arm 6 to cam the arm 12 downwardly and restrict movement of the closure 5.

Secured to the opposite end of the arm 12 is a weight 20 designed to normally hold the arm 12 in a horizontal position and restrict pivotal movement of the arm in a manner as described. The arm 12 is formed with a cut out portion defining a curved wall 21 adapted to contact with the lower bar 22 of the keeper 9 when the arm 12 is cammed downwardly by its contact with the keeper 9 point adjacent to the cut out portion 21,

thereof. The spring member 23 is former with a loop portion 26 to add resiliency to the spring member.

In the operation of the device, assuming that a door is moving towards the door check in a mamier as shown by Figure 1 of the drawing. With the arm 6 in this position, it is obvious that as the closure '5 moves towards its frame, the upper bar of the keeper rides over the inclined surface 19 of the upwardly extended portion 18 of the arm 12, causing the notch 21 to lie within the path of travel of the bar 22 of the keeper. It is obvious that as the bar 22 contacts with the wall 21 of the cut out po' 'tion,

notch 21 in the path of travel of the'bar 22,

which allows the closure to'move to a position within its frame.

Having thus described the invention, what is claimed as new is; l

A door check comprising a stationary arm, a pivoted arm having connection with the stationary arm, said stationary arm having a shoulder formed at one end thereof, said pivoted arm having a laterally extending pin adapted to-oontact withthe shoulder to restrict movement of the pivoted arm, said pivoted arm having an upwardly extending endportlon formed with. an. lncllned outer its inactive position.

wall, acurved wall tormed adjacentrto the", lower edge of the pivoted" arm, a spring member for normally holding the pivoted arm in parallel relation with the stationary arm, anarm supported by the movable element and including spaced bars, one of said bars adapted to move over the inclined Wall oi the pivoted arm to throw the arm downwardly to cause the opposite bar to, engage the curved wall-and retard movement of the movable element, and a weight on the pivoted-armtor moving the pivoted arm to In testimony that Iiclaim the foregoing asmy own,- I'v have hereto aflixed my; signature in the presenceof two witnesses.
